To all'whom it may concern: I Y BB-lU-kIlDWIl-thilt I, CHARLES M.REYNOLDS,

a citizen of the United' States, residing; at

Sparks-,in the county ofWashoe and State of Nevada, 7 have invented newand. useful Improvements in 'the Manufactureof-Briquets and otherArticles,- of which the following 1 is a specification.

This invention relates tothe manufacture of compressed charcoal'briquets froni sawdust-and other sawmill and timber waste, slabs orother refuse wood-tor organic vegetable substances; and-the recovery ofthevolatile constituents of the organic matter,

i into one end of-the'kiln or retort and .30

' kiln 'or' into any suitable type ofzbri suchlas' alcohol, creosote,tar, turpentine or theil1ke, freed therefrom by destructive dis- 7tillation."

In carrying my invention -into practice, the vegetable matterto betreated 1s first fed into a stationary or rotary kiln or retort, in

which it is wholly. or partially carbonized The volatile substancesdriven off fromthe material by this process of carbonization anddestruct ve -d1stillation are collected and conveyed tosuitable'receptacles for condensation and. the recovery of theby-products II1I1t10I1d'. Preferably the raw mater al, ma ground orcomnnn uted state, is introduced discharged from the oipposite end"thereof, the

v operation-being practically 'continuo1'1s,- and automatic incharacter. The carbon discharged from the kiln or retort, if notpreviously granulated or powdered isthen gran 'ulat'edor'reduce'd toasuitably comminuted state, aft'eluvl'iicli-tlie material' -is fedinto'a flr'nechainical miXen Where it is combined While still hot'Witl1-f .'Qm three to' five-per cent. of crude oil, coal tar, pitch orany suit; able one -ofthe .by-prod-ucts as .abinder; the
